The Republic of Serbia applied the booster dose of the following COVID-19 vaccines: BNT162b2 mRNA (Pfizer-BioNTech), Sinopharm BBIBP-CorV (Vero Cell®), Gam-COVID-Vac (Sput-nik V) and ChAdOk1 nCoV-19 (AstraZeneca). We aimed to examine the immunogenicity and reactogenicity of the booster dose and identify factors related to immune response and adverse events. Panel study, conducted during August and September 2021, included 300 persons receiving the booster dose at the Institute of Public Health of Serbia. Blood samples were taken on the day of receiving the booster dose, and after 7 and 28 days. When applying homologous regimen, the average increase in anti-spike immunoglobulin G was 8782.2 (after 7 days), 1213.9 after 28 days, while 9179.5 (after 7 days) and 16,728.1 after 28 days of heterologous regimen. Sinopharm BBIBP-CorV (p < 0.001) and Sputnik V (p < 0.001), age 65 and over (p = 0.001) and currently smoking (p < 0.001) were independently associated with lower levels of anti-spike immunoglobulin G. Female sex (OR = 1.77; 95%CI = 1.01–3.12), previous COVID-19 infection (OR = 3.62; 95%CI = 1.13–11.63) and adverse events after the second dose (OR = 2.66; 95%CI = 1.33–5.32) were independently associated with intense systemic adverse events 7 days after. Booster dose significantly increased antibodies titers, especially 28 days after heterologous regimen, without a significant increase in reactogenicity. © 2022 by the authors.

Background and Objectives: The issue of high rates of abortion among Serbian women has been previously highlighted, yet its social underpinnings are still not clear. The aim of this study was to investigate the lifetime use of and intention to use contraception among women after having an abortion. Materials and Methods: A cross-sectional study was carried out from 2022 to 2024 at the Clinic for Obstetrics and Gynecology, University Clinical Center of Serbia. The study participants were women who underwent induced abortions at the clinic. They filled in an anonymous questionnaire examining their demographic data, life-style and habits, medical history, lifetime use of contraception and intention to use contraception after their abortion. Results: A total of 433 women aged 16 to 49 years (mean age 32.0 years) participated in the study. In our sample, 81.1% of women had ever used contraception, with condoms being the most common, while 18.9% never used any contraception. Around 70% of women expressed the intention to use contraception post-abortion. Women who were of Serbian ethnicity, who had a higher level of education, who had no chronic illnesses and who already had multiple children were more likely to ever use contraception. Being of Serbian ethnicity, having higher education level and chronic illnesses and not smoking were associated with the intention to use contraception post-abortion. Conclusions: Most women who had abortions used contraception at least occasionally during their reproductive life and had the intention to start using it again. Therefore, women need to be continuously reminded by their gynecologists of contraception possibilities. © 2024 by the authors.

Background: Global rise in antibiotic utilization has been strongly associated with the resistance of bacteria to antibiotics. The COVID-19 saw an increase in the use of antibiotics in some countries. The aim of this study was to evaluate antibiotic utilization from 2006 to 2021 in the Republic of Serbia. Methods: Data on antibiotic use were retrieved from the national annual reports on the official website of the Medicines and Medical Devices Agency of Serbia during the period 2006 to 2021. To evaluate trends in the use of antibiotics in Serbia, linear, and joint regression analyses were performed. Results: The analysis of the antibiotics use over a sixteen-year period included a total of 50 antibiotics. A significant increase during the COVID-19 pandemic was observed for glycylcyclines that is, new-generation tetracyclines (tigecycline), third-generation cephalosporins (ceftazidime, ceftriaxone, and cefixime), respiratory fluoroquinolones (levofloxacin and moxifloxacin), carbapenems (ertapenem), and oxazolidinones (linezolid) utilization. Moreover, an almost negligible use of new β-lactam/β-lactamase inhibitors during the prepandemic period increased significantly during the COVID-19 pandemic period. Conclusions: A significant increasing trend in the use of specific antibiotics classified as the “Watch” and “Reserve” antibiotics during the pandemic period was observed. © 2023 Association for Professionals in Infection Control and Epidemiology, Inc.

Background: Previously a country with medium tuberculosis (TB) burden, Serbia almost reached a low TB burden during the period 2005 to 2015. Aim: The aim of this study was to analyse the trends in notification rates and treatment success rates as well as to identify predictors of treatment outcomes. Methods: We performed a trend analysis and logistic regression analysis of 17,441 TB cases registered from 2005 to 2015 in all health facilities in Serbia, to identify predictors of treatment success, loss to follow-up and mortality. Results: From 2005 to 2015, TB notification rate and mortality in Serbia decreased but treatment success remained below the global target. Loss to follow-up was associated with retreatment (odds ratio (OR) = 2.38; 95% confidence interval (CI): 2.08-2.77), male sex (OR = 1.57; 95% CI: 1.39-1.79), age younger than 65 years (OR = 1.37; 95% CI: 1.20-1.51), lower education level (OR = 2.57; 95% CI: 1.74-3.80) and pulmonary TB (OR = 1.28; 95% CI: 1.06-1.56). Deaths were more frequent in retreatment cases (OR = 1.39; 95% CI: 1.12-1.61), male patients (OR = 1.34; 95% CI: 1.19-1.52), those 65 years and older (OR = 4.34; 95% CI: 4.00-5.00), those with lower education level (OR = 1.63; 95% CI: 1.14-2.33) and pulmonary TB (OR = 2.24; 95% CI: 1.78-2.83). Conclusions: Special interventions should be implemented to address groups at risk of poor treatment outcome. © 2020 European Centre for Disease Prevention and Control (ECDC). All rights reserved.

Introduction: Between February and November 2016, 17 tuberculosis (TB) cases were identified among high school students in Novi Pazar, Serbia. The objectives of our study were to describe the outbreak, to identify potential risk factors and to evaluate the applied control measures. Methodology: The outbreak was described by time, person and place. A retrospective cohort study was conducted. Attack rates, unadjusted relative risks (RR) and 95% confidence intervals (CI) were calculated. Multiple log-binomial regression analysis was performed to calculate adjusted RR. Results: Sixteen of the total 17 cases occurred among grade 3 students, AR 5.5%. Previous TB family history, (RR = 5.29; 95% CI = 1.63-17.12), spending time with a known TB case at school (RR = 5.38; 95% CI = 1.48-19.55) and exposure to secondhand smoke (RR = 3.37; 95% CI = 1.11-10.29) were all significantly and independently associated with the occurrence of TB. Conclusions: Delayed diagnosis and reporting resulted in delayed initiation of the contact investigation and non-identification of latent TB cases probably favored the occurrence of this outbreak in a low incidence country. Public health authorities should consider revising the existing guidelines, promoting inter-sectorial collaboration and increasing awareness of public health professionals. © 2019 Stosic et al.
